I have the asterisks. The only problem i had with them were the blisters i was getting. The sleeves made them worse. I actually found some chaffing gel for women that i use now that helps. So I use the chaffing gel with no sleeves. As far a protection, they are great. Follow this link to read more.
I have a EVS on my "good" knee and a fitted CTI on my bad 1. There is absolutly no comparison which is better-the CTI. It fit sbeeter,supports better and doesn't hurt as much after the ride.
I got my insurance to pay for it also.
I was looking at the CTi....looks great but way expensive....I go see my ortho this week, maybe I can get my insurance to pay for it.........If not i think i will go with the Astreik
